At the time Dave Cook was leading a highly sensitive investigation into the murder of Daniel Morgan, a private investigator who was found in the car park of a south london pub 24 years ago with an axe buried in his head.

The Metropolitan Police Commissioner at the time, Sir (now Lord) John Stevens, was aware of the meeting, but no formal action by the police appears to have ensued.

Operation Tuleta

Now the Metropolitan Police, nine years on, is investigating the allegations.

In a statement to Channel 4 News they said:

“We can confirm that after MPS contact with solicitors representing the family of Daniel Morgan, officers from Operation Tuleta will examine the circumstances of a meeting that took place at New Scotland Yard in 2002.

“It is understood the meeting was in relation to concerns that a police officer working on the murder investigation was subject to surveillance.”
